Lady Gaga
Lady Gaga performs during the second day of the iHeartRadio Music Festival at the MGM Grand Garden Arena in Las Vegas, Nevada September 24, 2011. The festival marks the official launch of iHeartRadio, Clear Channel's free digital radio product combining more than 800 broadcast radio and digital-only stations from 150 cities.

Lady Gaga has been warned by friends that new lover and The Vampire Diaries star, Taylor Kinney will break her heart.

A source told America's Star magazine: "All of her friends are telling her to watch her step - Taylor is bound to break her heart. It's only a matter of time before he finds someone else."

Taylor's ex, Brittany Sackett told of how she had still been in a relation with Kinney when Gaga first started dating him when they met on the set of the video shoot for her next single 'You and I'.

Sackett said: Brittany said: "She was with my boyfriend, and I found out he was cheating on me."

Gaga wrote her latest single about ex-lover Luc Carl and is a firm believer in the correlation between singing a song well and writing it yourself.

She explained: "There is not one song on any of my records that wasn't written by me, and I think when you write your own music you find ways to reinvent [the songs] emotionally through yourself and performance so that they are different every night and that song you know, sometimes it's about the guys and sometimes it's about the fans."
